Don't be mistaken; the dealership is not the only stop to make when buying a new car. Financing rates of 0% may look appealing at first, but they often last for no more than a few months, after which the interest rate skyrockets.Explore your options. You may discover that getting a loan will cost less than financing directly. If you do find a loan that you like, it's recommended that you get approved for it before buying the car. This will speed up the whole car-buying process.
